clicking on selectitem dropdown arrow causes icon "on click" to fire

[gsaxena]

When using a dynamic form which has selectItems that in turn have icons, I've noticed that if a user clicks on the "down arrow" of the selectItem, it will cause an "on click" even to be triggerred on the icon. (This problem dissapears if the user clicks on the middle of the selectItem box instead of the actual arrow itself.) Is this a bug? My hunch is that there is some sort of "overlap" or "lack of resolution preciseness" which is causing the clicking on the drop-down arrow of the selectitem to also cause an event that is treated as a click on the nearby icon. (In case it helps, I played with cellpadding etc., but that has no effect. And in any case, we like the look of cellpadding = 0.)
